Exploring the question

What if there were no friction?

Jennifer lives in a world that would seem very strange to us. Everything is very slippery, like ice. All of the surfaces have very little friction. Friction is the name given to the force that makes something slow down when it is sliding across another surface.

Jennifer is used to her world with very little friction, but we would have trouble.

Use pictures or words to describe what it feels like to walk around on ice.
